Laptops tend to lose their charm quickly when you’re constantly looking for the nearest power outlet to charge up. How do you keep your battery going for as long as possible?
当你不断寻找最近的电源插座充电时，笔记本电脑的魅力很快就会消失。你是如何让电池尽可能长时间地持续使用？
1. Defrag regularly - The faster your hard drive does its work – less demand you are going to put on the hard drive and your battery. Make your hard drive as efficient as possible by defragging it regularly. (but not while it’s on battery of course!)
1. 定期碎片整理 ——硬盘工作越快，硬盘和电池的负载就越小。通过定期碎片整理，尽可能高效地提升硬盘效率。（当然，电池开着的时候不行！）
2. Dim your screen – Most laptops come with the ability to dim your laptop screen. Some even come with ways to modify CPU and cooling performance. Cut them down to the lowest level you can tolerate to squeeze out some extra battery juice.
2. 调暗屏幕 ——大多数笔记本电脑都配备了调暗功能。有些甚至还自带了修改 CPU 和散热性能的方法。把电池降到你能忍受的最低电量，这样可以挤出额外的电池电量。
3. Cut down on programs running in the background. Itunes, Desktop Search, etc. All these add to the CPU load and cut down battery life. Shut down everything that isn’t crucial when you’re on battery.
3. 减少后台运行的程序。iTunes、桌面搜索等。这些都会增加 CPU 负载，降低电池续航。电池用电时关闭所有非关键设备。
4. Cut down external devices – USB devices (including your mouse) & WiFi drain down your laptop battery. Remove or shut them down when not in use. It goes without saying that charging other devices (like your iPod) with your laptop when on battery is a surefire way of quickly wiping out the charge on your laptop battery.
4. 减少外部设备 ——USB 设备（包括鼠标）和 WiFi 会消耗笔记本电脑电池。不用的时候请移除或关闭它们。不用说，在电池使用时用笔记本电脑给其他设备（比如 iPod）充电，是快速耗尽笔记本电池电量的可靠方法。
5. Add more RAM - This will allow you to process more with the memory your laptop has, rather than relying on virtual memory. Virtual memory results in hard drive use, and is much less power efficient. Note that adding more RAM will consume more energy, so this is most applicable if you do need to run memory intensive programs which actually require heavy usage of virtual memory.
5. 增加内存 ——这样你就能用笔记本现有的内存处理更多内容，而不是依赖虚拟内存。虚拟内存会消耗硬盘，且能耗大大降低。注意，增加内存会消耗更多能量，所以如果你需要运行需要大量虚拟内存的内存密集程序，这一点尤为适用。
6. Run off a hard drive rather than CD/DVD - As power consuming as hard drives are, CD and DVD drives are worse. Even having one in the drive can be power consuming. They spin, taking power, even when they?re not actively being used. Wherever possible, try to run on virtual drives.
6. 使用硬盘而非 CD/DVD - 硬盘虽然耗电，但光盘和 DVD 驱动器更耗电。即使硬盘里有一个，也会很耗电。它们旋转，获取力量，即使它们没有被主动使用。尽可能在虚拟硬盘上运行。
7. Keep the battery contacts clean: Clean your battery’s metal contacts every couple of months with a cloth moistened with rubbing alcohol. This keeps the transfer of power from your battery more efficient.
7. 保持电池接触点清洁 ：每隔几个月用沾有酒精的布清洁电池金属接触点。这能让电池的电力传递更高效。
8. Take care of your battery – Exercise the Battery. Do not leave a charged battery dormant for long periods of time. Once charged, you should at least use the battery at least once every two to three weeks. Also, do not let a Li-Ion battery completely discharge. (Discharging is only for older batteries with memory effects)
8. 照顾好你的电池 ——锻炼电池。不要让充电好的电池长时间处于休眠状态。充电后，至少每两到三周使用一次电池。另外，不要让锂离子电池完全放电。（放电只适用于带有记忆效应的老电池）
9. Hibernate not standby – Although placing a laptop in standby mode saves some power and you can instantly resume where you left off, it doesn’t save anywhere as much power as the hibernate function does. Hibernating a PC will actually save your PC’s state as it is, and completely shut itself down.
9. 休眠非待机 ——虽然将笔记本置于待机模式能节省一定电力，且可以立即从中断处恢复，但它在节电效果上远不及休眠功能。休眠电脑实际上会保存电脑的状态，并且会完全关闭。
10. Keep operating temperature down - Your laptop operates more efficiently when it’s cooler. Clean out your air vents with a cloth or keyboard cleaner.
10. 保持工作温度较低 ——你的笔记本在凉爽时运行更高效。用布或键盘清洁剂清理通风口。
11. Set up and optimize your power options – Go to ‘Power Options’ in your windows control panel and set it up so that power usage is optimized (Select the ‘max battery’ for maximum effect).
11. 设置并优化电源选项 ——在 Windows 控制面板的“电源选项”中设置，使其能用电最优（选择“最大电池”以获得最大效果）。
12. Don’t multitask – Do one thing at a time when you’re on battery. Rather than working on a spreadsheet, letting your email client run in the background and listening to your latest set of MP3s, set your mind to one thing only. If you don’t you’ll only drain out your batteries before anything gets completed!
12. 不要多任务处理 ——电池充电时一次只做一件事。与其做电子表格，让邮件客户端在后台运行，听你最新的 MP3，不如专注于一件事。如果不这样做，你只能在完成之前耗尽电池！
13. Go easy on the PC demands – The more you demand from your PC. Passive activities like email and word processing consume much less power than gaming or playing a DVD. If you’ve got a single battery charge – pick your priorities wisely.
13. 对电脑的要求要宽松 ——你对电脑的要求越高。像电子邮件和文字处理这样的被动活动，比玩游戏或玩 DVD 耗电要少得多。如果你只有一块电池电，请明智地选择优先事项。
14. Prevent the Memory Effect - If you’re using a very old laptop, you’ll want to prevent the ‘memory effect’ – Keep the battery healthy by fully charging and then fully discharging it at least once every two to three weeks. Exceptions to the rule are Li-Ion batteries (which most laptops have) which do not suffer from the memory effect.
14. 防止记忆效应 ——如果你使用的笔记本电脑非常老旧，你需要防止“记忆效应”——通过至少每两到三周充满电再完全放电来保持电池健康。例外的是锂离子电池（大多数笔记本都有），它们不会有记忆效应。
